To all whom. it may concern Be it known thatlt, Josnrn- 1B. MARTIN, a citizen of the .United States, residing at lEvanston. in the county of Uinta and State of Wyoming, have invented certain new and useful Improvements in Coasters, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in coasters, and particularly to that class of coasters which are wheeled and steerable.

An object of this invention is the provision of a coaster which comprises a platform supported at its ends upon wheels, the front wheels being mounted in rotatable yokes, the yokes being connected by a steering bar to which is connected, at its-lower end, an upstanding steering post, the coaster also'including a seat elevated from the platform at its rear end, whereby a person seattilt) ed upon the seat may readily steer the coaster in any desired direction by rotating the steering rod.

Another object of this invention is the provision of a coaster which includes a seat which is adjustably supported on a rearwardly inclined seat bar, the seat being dis-' posed above the platform of the coaster at its rear end and the seat bar engagingthe platform forwardly of its center so that the weight of the person on the seat is forwardly of the center of the platform to prevent the platform from tipping over backwardly.

A still further object of this invention is the provision of a coaster which includes aseat which is elevated above the platform at its rear end to a suitable height so that the person may reach the ground with either foot to propel the coaster, the. steering post being disposed in a vertical position so that the steering wheel on the upper end thereof may be easily engaged by the hands of the ;the seat is foot.

person upon the seat, the steering post being used as a push rod when the person upon propelling the coaster with either Withthese and other objects in view, my invention consists in the novel construction; combination, and arrangement of parts to be hereinafter more fully described, claimed,

and illustrated in the accompanying drawing, in which, I

Figure 1 is a side elevational View, partly in section of my improved coaster; Fig. 2 is a fragmentary bottom plan view thereof; and Fig. 3 is a detail view showing the manner of connecting the seat bar to the platform.

Referring more particularly to the drawing, the numeral 1 designates the platform of my improved coaster-,and mounted in yokes :2 at the rear end. of the platform, are the supporting wheels 3, the yokes 4t Patented Web. 11d, 11%.5. Application filed may 16, 191%., Serialltfo. 833,096.

at the forward end of the plaform being provided with upwardly extending stub shafts 5 which project through openings 6 in the platform and are connected to the blocks 7 on the upper face of the platform.

Extending rearwardly from each of the yokes -l is an arm 8, and connected at its opposite ends to the arms is a steering bar 9. Rotatably. mounted at its lower end-in an. opening in the platform, adjacent its forward end, is a steering postlO, the lower post prQ ecting below the extremity of the lower face of the platform and being connected to the steering bar by a suitable angle arm 11, whereby upon rotation of the post,'

the steering bar is moved from side to side to simultaneously turn the steering wheels. A wheel 12 is keyed -to the upper end of the steering post 10, whereby-the post may be readily turned to steer the coasterin any desired direction.

Formed in the platform forwardly of its center, is a longitudinal slot '13, and secured to the under face of the platform forwardly of the slot, is a wearing plate 14, and a wearing plate 15 is connected to the upper face of the platform rearwardly of the slot 13, the opposite ends of the plate 15 being directed inwardly, and the extremities of the plate being bent upwardly in spaced relation to each other to provide supporting lugs lG-in which horizontally alined openings 17 are formed. Disposed through theslot 13 is the front section 18 of aseat bar 19, the front section being provided at its forward extremity beneath the platform with'a toe 20 for engagement against the wearing plate 14 on the under face of the platform, and the bar being provided adjay 1 1 cent its rear'endwith a heel 21 for engagev mentagainst the wearing plate on the upper face of theplatform, the section 18 being also formed with an opening 22 thereinQadjacent the heel portion, the opening being adapted toregister with the openings 17 in-the lugs 16 for the reception of a-bo'lt 23, by means of which the front section of the seat bar is'pivotally connected to the platform. Pivot-ally connected to the rear extremity of the front/section: 18

'is the rear section 2% of the seat bar 19,- the rear' section 24 carrying a U-shaped .plate 25 for engagement against the lower edgeof theffr'ont section 18, to hold the rear section of the bar in an inclined positionso that therear extremity of the rear section is disposed above the platform. A

vertically disposed slot 26 is formed in the enlarged rear end of thesection 24 of the seat bar, the slot being adapted-to receive the standard 27 of aseat 28,the standard having a series of openings 29. therein with one of which the bolt 30 which projects 25 adapted to engage, to hold the seat in any through the slot 26 in the seat bar, is

desired vertically adjusted position with When the coaste'r reaches the bottom of the incline, it is'only necessary for, the'person upon-the seat to drop one foot over the side 5 of the platform to the ground, and propel 4 relation to the platform. Projecting from the opposite side edges of the platform at its 30 thegcoaster' by striding with the foot and using the steering post as a push rod. It

"will, of colirse, be seen that, if desired, both feet may be placed upon the ground on opposite sides of'the platform, the coaster being propelled by' the user sothat 'both feet are used to propel the coaster as though the person were walking. t

Having thus fully described my inven--.

tion, what I desire to claim and secure by Letters Patent, is

1. A" device of -the class described comprising a wheeled platform having a 'central' a longitudinal slot formed therein, a rearwardly'inclined seat bar pivotally connected to the platformand projecting at its forward end through said slot, the forward p the rear end of the seat bar.

extremity of the seat bar being adapted to engage the under face of the'platform. forwardly .of the slot, and a seat carried by 2. A device of the class described com prising a wheeled platform, having a central longitudinal slot formed therein, a rearwardly inclined jointed seat bar, the forward section of said seat bar being pivotally connected adjacent'its rear end to the platform rearwardly of, the slot, said forward section projecting through the slot and having its forward end engaged against the under face of the platform forwardly of the slot, means for holding the rear section of i the seat bar in longitudinal alinement with the forward. section thereof, and a seat carried uponthe rear end of the rear section of the seat bar. I

3. A-device of the class described comprising a platform, supporting wheels connected to said platform at its rear end, steering wheels connectedto said platform at its forward end, an upstanding steering post operatively connected with said steeringwheels, said platform having a central longitudinal slot formed therein adjacent its forward end, a rearwardly inclined seat bar projecting at its forward end through said engagement beneath the platform forwardly of the slot, a heel :portion for engagement against the upper face of the platform rearwardly of'the slot, and a seat carried by the upper end of said seat bar.
